U-joints are found in your car's driveshafts and they allow each shaft to bend and move in different directions while transmitting power from one end to the other. Symptoms of a defective U-joint include loud clanking noises, especially when shifting from reverse to drive, and vibrations that increase as your vehicle accelerates. An Impala U-joint replacement from AutoZone eliminates those problems and prevent bigger ones from occurring.
